Random checks catch 99 tipsy Indian pilots since 2011

The revelation could fuel questions about about airline discipline and whether safety procedures in India's fast-growing industry need to be tightened further.

"Since 2011 a total of 99 pilots, including the 10 (so far this year), have been grounded for testing positive in pre-flight medical examination for alcohol consumption," aviation minister G.M. Siddeshwara told Parliament.

The minister did not divulge the names of the airlines involved or any other details, according to the report from the Press Trust of India news agency.
